iolo System Mechanic review

When it seems that your PC runs slowly or key/mouse response is delayed, it is often a software-related issue that can be easily solved. One way is to use Windows system maintenance tools if you have time and skills, the alternative is various optimization tools. Those do the job getting rid of obsolete apps, bad registry entries, system errors etc. System Mechanic is a set of PC system utilities, also known as PC optimization software, that helps manage and maintain devices in good shape.

Installation & Interface

For review we took the Pro version, downloaded from the official website, so this could be perceived as iolo System Mechanic Pro review. This is the most complete and effective package. It repairs issues, boosts PC speed, as well as cleans, protects and secures to speak generally. Additionally, it blocks malware and bloatware, it could recover lost data.

We should mention right away that System Mechanic might not be good friends with antivirus or antimalware program. But this problem appears only if you use built-in antivirus and firewall. Then, the process is typical: enter email address and get an activation key… no additional software, no other difficulties.

When you run the optimizer for the first time, you are prompted to analyze the system. On the left, there is a menu with the following entries: Dashboard, Toolbox, ActiveCare, LiveBoost, Security. Dashboard tab contains Overview and Issues sections, and Overview is where you choose system analysis type – deep or quick. Service Status indicates trial time left in a free version, or available upgrades to install in Pro.

Issues tab is pretty self-explanatory. Toolbox contains 6 more sub-tabs: All-in-one (multiple functions arranged via wizards), Clean, Speed up, Protect, Recover, Manage. Each of them contains a set of proper tools for corresponding purpose. Active Care serves to configure automatic optimization, repair and maintenance of PC. RAMJet maximizes available memory, modes in PowerSence help to boost performance depending on what apps are running, and so on.

Security tab allows to adjust anti-malware features, enable/disable System Mechanic monitoring, as well as setting up firewall. Real-time boost tab contains info on issues, energy efficiency, system reliability and PC status.

Overall, interface is convenient, features are laid out logically and easy to find. We did not encounter any advertisements, pop-ups etc., unlike in many other products. In the new version of System Mechanic tool tips were redesigned. Instead of pop-ups to click, now feature descriptions are directly visible in the interface.

Tip. Use the “Switch color theme” button on the top panel to change the color scheme to white or black.


Now let’s discuss the central point of System Mechanic: functionality, what is there to optimize PC work and how it actually works. There are several areas. Active system tune-up includes optimization, repair and security tools.

These are actions to optimize PC startup, registry, configure Internet connection, system drive, detect and fix errors/broken shortcuts, etc. Security actions include detecting vulnerabilities, backing up registry every 14 days, disabling Windows 10 telemetry, wiping all data from a drive and permanently remove files. Below is the summary.

System Mechanic Pro

Exclusive features. As we said, in addition to basic optimization and PC health tools, there’s malware blocking (only in Pro) and bloatware removal – to detect startup programs that launch without permission. But System Mechanic claims to offer several more patented technologies, such as:

  1. ActiveCare – that finds and fixes problems on PC when it is not in active use;
  2. Program Accelerator – a calibration technology to ensure the fastest possible access to files;
  3. Startup Optimizer – that uses research-based classifications to identify issues;
  4. LiveBoost – to find patterns and prioritize programs to clean RAM, and so on.
  5. ByePass – secure password storage for Chrome and Firefox
  6. Privacy Guardian – removes web surfing traces in browsers.
  7. Drive Scrubber – wipes deleted data on disks. Allows up to 99 rewrite cycles.

Testing and how it worked for us

Deep scan detected about 5 GB of junk files related to the Windows and 465 MB of Internet activity traces. It also corrected privacy vulnerabilities  and accelerated Internet connection speed by about 15%. The new System Mechanic has become much more convenient to use in comparison to its previous versions. The main parameters are available in the main window and on the top panel, which speeds up access to the main functions.

Also the time needed to scan was reduced. Deep scan on our test PC was completed in about 5 minutes, and a quick scan in 2 minutes. After it was finished, we also ran Disk Analyzer and it pointed out another 193 Mb of junk files. The integrated antimalware solution has a high degree of detection and quickly blocks detected threats. In our test, 16 out of 18 test files were blocked, including PUA and compressed files.

In conclusion

In total, System Mechanic helped to free up almost 5.5 GB on the hard drive and about 1% of RAM. We didn’t notice a considerable improvement in PC performance or speed of tasks, but it’s individual for every system. Design, interface and UX are convenient and offer a great single tool to monitor and manage everything on a PC. Unstable performance was the main disadvantage of previous versions of System Mechanic. The program often crashed, and some functions didn’t work correctly. New engine solved these problems, in any case, for several days of tests, we haven’t notice any errors. Current bottom line: System Mechanic is perfect for removing junk files and freeing disk space. Also it has effective antimalware module however it isn’t ideal in boosting PC speed or performance though.
